The excerpt for table reads.
Tables are used to display tabular data in HTML.
That tag wiki is not specific to HTML. The last edit to the excerpt was a bad one.
The part about not using them with relational databases only relates to databases. Tagging things as mysql and table doesn't make much sense, because it's generally understood that MySQL uses database tables.
I added the HTML parts to it because I knew about them and that tag was very common. It was never meant to convert the tag to be HTML-specific. I would much rather see the appropriate HTML questions moved over to html-table because table in itself is very ambiguous.
Can't fit this in a comment...
As the person who suggested the (approved) edit to the excerpt of table I'd just like to explain my reasoning.
To quote from the tag wiki:
It seemed really rather pointless and counter-productive to have the following in the excerpt:
I happen to agree with animuson's original edit to the wiki and his answer above. Using the tag table in the context of a relational database is fairly ridiculous. It's more than implied by the fact that a database is being used. I therefore changed the excerpt to exclude mention of databases rather than altering the wiki to indicate that table was appropriate for them.
I, obviously, disagree with the characterisation of the edit to the excerpt as "bad" :-).
Personally, I'm with the OP and animuson on this html-table makes much more sense. If the tag is not meant to related solely to HTML tables (and the tag html-table exists) then the excerpt should, maybe, be changed to something like this?:
Though "Tables are used to display tabular data" is a fairly obvious statement to make.
